I did it with both boys.
About 17 weeks I had a massive feedathon with both boys, which meant they fed All The Time for about a week [knackered]
But then they settled and fed far less frequently.
And I found it quite depressing in many ways to move onto food, really. SO much easier to stuff them up your top and continue chatting without breaking stride
Sleep - DS1 slept well from about 4.5m to about 5.5m and then he started cutting teeth. He then started getting horribly high temperatures each time he cut a tooth from when he was one, which dramatically affected his sleep.
I don't think food amounts have ever affected my children's sleep, truly. Teeth, yes. DS1 slept through fairly reliably from 19m and was cheerfully taking his bear and his drink up for a nap in the late morning/early afternoon at that age too. DS2 is 16m...and we won't talk about it...
Neither of them ate a great deal when they first started eating food - DS1 probably upped his food intake about 9m but DS2 not till more like 10. Both now could eat at County level...!
So no, I didn't do lots more feeds, apart from around the 17 week mark, as I said. DS1 I gave food to at 6m, but DS2 was 27+3 when he first had anything, because it was in the massively hot weather last summer and I didn't want to introduce him to food when it was 90 degrees because I felt it might interfere with his fluid balance in the heat - I didn't want him constipated, for instance.
